Telerik的的WinForms RadGridView創建和運行時填寫

Question

我的問題是這個

Fill RadGridView dynamically

非常相似，但我不希望創建數據表

這是網格視圖

GridView = new RadGridView 
      { 
        AutoSizeRows = true, 
        BeginEditMode = RadGridViewBeginEditMode.BeginEditProgrammatically, 
        Location = new Point(0, 130), 
        Name = "GridView", 
        ShowRowErrors = false, 
        Size = new Size(390, 100), 
        TabIndex = 0, 
        Visible = false 
      }; 

這方法在運行時創建列

private List<GridViewTextBoxColumn> InitializeColumns() 
    { 
     var result = new List<GridViewTextBoxColumn>(); 

     { 
      var columnId = new GridViewTextBoxColumn 
       { 
        Name = "RecordID", 
        HeaderText = "ID", 
        FieldName = "RecordID", 
        MaxLength = 50, 
        Width = 50, 
        DataType = typeof(int) 
       }; 
      result.Add(columnId); 
     } 

     { 
      var columnInformation = new GridViewTextBoxColumn 
       { 
        Name = "RecordInformation", 
         HeaderText = "Information", 
         FieldName = "RecordInformation", 
         MaxLength = 50, 
         Width = 250, 
         DataType = typeof(string) 
       }; 
      result.Add(columnInformation); 
     } 

     { 
      var columnRowType = new GridViewTextBoxColumn 
      { 
       Name = "RecordType", 
       HeaderText = "Type", 
       FieldName = "RecordType", 
       MaxLength = 50, 
       Width = 250, 
       DataType = typeof(string) 
      }; 
      result.Add(columnRowType); 
     } 

     return result; 
    } 

這個類是網格行

internal class OrderTripChangedAlertItem 
{ 
    public int RecordID { get; set; } 
    public string RecordInformation { get; set; } 
    public string RecordType { get; set; } 

    public OrderTripChangedAlertItem(int recordID, string recordInformation, string recordType) 
    { 
     RecordID = recordID; 
     RecordInformation = recordInformation; 
     RecordType = recordType; 
    } 
} 

所以我的列表綁定到網格視圖。列顯示正常，但沒有顯示數據。必須有一個記錄。我錯過了什麼？

這裏是整個代碼我放在一個表格上，這工作得很好：

protected override void OnLoad(EventArgs e) 
    { 
     base.OnLoad(e); 

     RadGridView GridView = new RadGridView 
     { 
      AutoSizeRows = true, 
      BeginEditMode = RadGridViewBeginEditMode.BeginEditProgrammatically, 
      Location = new Point(0, 130), 
      Name = "GridView", 
      ShowRowErrors = false, 
      Size = new Size(390, 100), 
      TabIndex = 0, 
      //Visible = false, 
      Parent = this 
     }; 

     GridView.Columns.AddRange(InitializeColumns().ToArray()); 

     List<OrderTripChangedAlertItem> list = new List<OrderTripChangedAlertItem>(); 
     OrderTripChangedAlertItem item = new OrderTripChangedAlertItem(0, "some info", "some type"); 
     list.Add(item); 
     GridView.DataSource = list; 
    } 

    private List<GridViewTextBoxColumn> InitializeColumns() 
    { 
     var result = new List<GridViewTextBoxColumn>(); 

     { 
      var columnId = new GridViewTextBoxColumn 
      { 
       Name = "RecordID", 
       HeaderText = "ID", 
       FieldName = "RecordID", 
       MaxLength = 50, 
       Width = 50, 
       DataType = typeof(int) 
      }; 
      result.Add(columnId); 
     } 

     { 
      var columnInformation = new GridViewTextBoxColumn 
      { 
       Name = "RecordInformation", 
       HeaderText = "Information", 
       FieldName = "RecordInformation", 
       MaxLength = 50, 
       Width = 250, 
       DataType = typeof(string) 
      }; 
      result.Add(columnInformation); 
     } 

     { 
      var columnRowType = new GridViewTextBoxColumn 
      { 
       Name = "RecordType", 
       HeaderText = "Type", 
       FieldName = "RecordType", 
       MaxLength = 50, 
       Width = 250, 
       DataType = typeof(string) 
      }; 
      result.Add(columnRowType); 
     } 

     return result; 
    } 

    internal class OrderTripChangedAlertItem 
    { 
     public int RecordID { get; set; } 
     public string RecordInformation { get; set; } 
     public string RecordType { get; set; } 

     public OrderTripChangedAlertItem(int recordID, string recordInformation, string recordType) 
     { 
      RecordID = recordID; 
      RecordInformation = recordInformation; 
      RecordType = recordType; 
     } 
    }
